The City of Roseville is beginning the design phase of a roadway reconstruction project testing a new paving material called Roller Compacted Concrete (RCC). Hickory Street, from Church to Oakland, has been identified as an ideal candidate to test this new pavement. The current failing asphalt roadway will be replaced with a new concrete surface. Work is planned for spring/summer 2017.
Residents received information in the mail about the proposed project and a voting ballot. A community meeting was also held on Wednesday, October 28, 2015 to discuss the pilot project with the community and answer questions. Because 90% of the residents voted in favor of the project, it will be moving forward.
The pilot project includes two other locations so varying construction techniques, traffic conditions, and finishes can be examined. These locations are: – Washington from Pleasant Grove to just north of Mountain Park Drive – Atkinson, from Church Street, through and including Denio Loop
The City maintains about 1,000 lane miles of asphalt roadway. Proper asphalt preventative maintenance requires maintaining 100 lane miles per year at a cost of about $8.5 million. The City has on average $4.4 million per year available for roadway maintenance—about half of what is needed. This gap in funding is called the roadway maintenance structural deficit.
Road maintenance funds generally come from the Gas Tax paid at the pump. The City of Roseville completed a cost analysis comparing the replacement of failed asphalt roads with either a new asphalt roadway or a new roller compacted concrete (RCC) roadway. The result showed RCC construction costs are about the same or lower than that of asphalt construction, but the maintenance costs for RCC are significantly lower.
RCC can operate for 20 to 25 years without maintenance, while asphalt construction requires resurfacing every 7 to 10 years. If we reconstruct the city's deteriorating roadways with RCC, the funds that would have been used to resurface those roads had they remained asphalt, can now be used to repair the city's remaining asphalt roadways. This will help reduce the roadway maintenance structural deficit.
The benefits of RCC are unique and pleasing aesthetics, reduced maintenance, fewer resurfacing projects impacting your neighborhood, cooler roads during the day, and brighter roads during the night.
